Bridge? There’s your problem I think. Bridge doesn’t allow ingress to individual IPs. In bridge, you tell each container what port it listens on, then access it from the IP of the host.
User defined bridges act differently from the default one as well. May not be relevant to your issue, but https://docs.docker.com/engine/network/drivers/bridge/#differences-between-user-defined-bridges-and-the-default-bridge
Oh, hmm. How are you telling which service to be on which IP then? Could you safely post your compose file?
